Dont bother with the relay. The fix is an electrolytic capacitor 35v 1700uF wired in parallel with the power/ground going to the ballast. This is the solution for any car using can-bus (bmw,dodge,audi) can-bus is very sensitive to resistance changes. I struggled with my kit for 2 weeks until i found out about the cap on a bmw forum. All the searches and info I got on AW and vwvortex were wrong: Vag-com does nothing unless you get oem lights. Relays cause light out errors b/c the relay has different resistance than a 55w halogen. You dont need a relay b/c i measured with a volt meter and ballasts get plenty of power. The lights would also flicker when the high beams were turned on. Hid flicker is caused by can-bus turning power on/off because it sees incorrect resistance. Don't stress about getting an aftermarket kit. It will work and its a very easy install if you use the cap.
